IMPROVEMENT IN CENTRIFUGAL LIQUORING APPARATUS.

Specification forming part of Letters Patent No. 221,807, dated November18, 1879; application filed September 2, 1879.

To all whom it may concern:

Be it known that l', AUGUSTE A. GoUBER'r, of the city and State of NewYork,.liave invented certain Improvements in Centrifugal LiquoringApparatus, of which the following is a specification.

My improvements relate to the class of apparatus employed to conductprescribed quantities of white liquor from the central cham-` ber orreservoir of a centrifugal machine, witbout allowing the escape of suchliquor otherwise than through the sugar contained in the molds; and myinvention consists in establishing in the outer portion of the basket aseries of cells separated from each other by means of vertical wallsprojecting inward from the rim of the basket toward the spindle, andprovided at the top with a removable annular cover, preferably composedof two or more segments.' The sugar-molds are loosely deposited inthecells and their outer open faces bear against a quadrangular frame,to which a perforated diaphragm is affixed. This frame is looselydeposited in the mouth of the cell adjoining the rim, and has its outerbearingl upon a gasket of elastic material affixed to the inner face ofa shoulder, the sides ot which are formed by projections from thedivisionwalls, the bottom by an upward projection i froin the oor of thebasket, and the top by a l provide underneath the Hoor of the basket anannular collecting-chamber, into which any excess of liquor remaining inthe basket can be drained, and from which it can be discharged by meansof suitable faucets.

The accompanying drawings, representing a centrifugal machine embodyingmy improvements, are as follows: Figure l is a top view,

partly in horizontal section through the line :r m on Fig. 2, which is acentral vertical section through the line y y on Fig. l.

The drawings represent the usual basket A of a centrifugal machine,mounted upon the vertical spindle B and divided into a series of cells,C, by means of the radial partition-walls c.

It will be seen that the partition-walls extend outward to the rim a ofthe basket, and that at the outer mouth of each cell there is providedan inwardly-projectin g shoulder, the sides of which are contributed bythe projections c cast upon or otherwise affixed to the outer portionsof the partition-walls, the bottom of which is contributed by theprojection a2 in the Hoor of the basket, and the top by the bar c2extending across the upper outer edge of the cell. der is provided withthe elastic gasket d, which affords the bearin g for the quadrangularframe E, to which the perforated diaphragm e is affixed.

It will be seen that the bottom of each cell isa plane, which isoutwardly and downwardly inclined to make it conform to the inclinationof the bottom of the mold F.

Beneath the door ot' the basket I provide a collectinglchamber, G, intowhich liquor contained in the basket may be drained, when the machine isstationary, through the inwardly and downwardly inclined channels ortubes g formed or inserted in the bottom of each cell. The escape ot'the liquor over the top of the rim of the basket is prevented by meansof the removable annular plate H, which is preferably composed ot' twosegments, It 7L, each provided with the packing-strips h and h2, bymeans ot' which a tight jointis made when the plates are screwed orclamped down upon the tops of the partitions and the rim of the basket.

The collecting-chamber G is provided with faucets g', by means of whichthe iuid therein contained can be drawn off when desired. The centralportion of the basket may be left open,

The inner face of this shoulor the usual central reservoir may bemounted eral cells therefrom by means of the usual spouts.

The escape of whiteliquor from the machine otherwise than through thesugar contained in the molds has heretofore been prevented by meanssomewhat analogous to those which I employthat is to say, movable cellsor liquoring-boxes have been employed which, under the influence ofcentrifugal action, were driven radially outward, making tight joints,respectively, with the inner open faces of the molds.

In the present case it will be observedlthat centrifugal force isutilized for the purpose ofA packing a joint through which white liquorwould otherwise escape; butinstead of a movable cell or liquoring-box Iprovide a stationary cell and effect the necessary packing of the jointby means of a gasket in front of a mold free to move outward underthe action of centrifugal walls. The partition-walls G maybe dispensedwith, and therim of the basket be m ade polygonal, with a number ofsides equaling the number of molds, the gaskets in such case beingaffixed either to the outer open faces of the molds or to the edges ofthe several sides of the polygonal rim, when they will be respectivelyengaged by the outer' edges of the molds or the gaskets may be affixedto the inner side of a concentric rim, and the outer faces of the moldsbe rounded to conform to the shape of the rim.

In either case the thrust outward of the molds eHects the compression ofthe gaskets and prevents the escape of liquor except through theinterior of the molds.

I claim as my inventionl. In centrifugal liquorin g apparatus, a seriesof sugar-molds loosely contained in the basket of a centrifugal machine,in combination with a series of quadrangular gaskets of elastic materialrespectively interposed between each mold and the perforated rim of thebasket,

whereby when the machine is rotated the molds are driven radiallyoutward by centrifugal force and the gaskets are compressed, thuspreventing the escape of liquor from the machine otherwise than throughthose portions of the perforated rim of the basket immediately oppositethe outer open faces of the molds.

2. The basket A, provided with the vertical partitions C, extendinginward from the rim, and witha removable annular cover, H, incombination with the collecting-chamber G, communicating with the spacesor cells between the partitions by means of the inwardly and downwardlyinclined passages or tubes g. substantially as and for the purpose setforth.
